Summary
Body weight of triplet individuals at one year of age was analysed. Mean body weight was heavier in males than in females, and the heaviest in the first-born followed by the second-born and the third-born in this order, which were also seen in that at birth. The contribution of gestational age was greater than maternal age to the growth rate of total body weight from birth to one year of age.
